	  Saying Y here will include support for the DNS Resolver key type
	  which can be used to make upcalls to perform DNS lookups in

	  DNS Resolver is used to query DNS server for information.  Examples
	  being resolving a UNC hostname element to an IP address for CIFS or
	  performing a DNS query for AFSDB records so that AFS can locate a

	  DNS Resolver is used by the CIFS and AFS modules, and would support
	  SMB2 later.  DNS Resolver is supported by the userspace upcall
	  helper "/sbin/dns.resolver" via /etc/request-key.conf.

	  See <file:Documentation/networking/dns_resolver.rst> for further
